Have any of you played Legend of Grimrock? Most of you younger players probably wouldn't like it, but for those of us who cut our teeth on the old pre-Windows DOS RPG's, it does have its appeal. I'm playing it in Windows 7, but I think it also works in XP. (Alas, it's Steam.)
You start out with a party of four(!) It uses some mouse commands, but movement/fighting is WSAD keyboard. I haven't got that far, but I think it also features turn-based combat. (For those of you who go REALLY far back, there's an option to turn off the auto-map (which works sort of like the one back in the second Elder Scrolls game.) I no longer have my stacks of graph paper, so I opted for the auto, thank you very much.
The whole thing sort of reminds me of Might and Magic II.
